Filed: 1983-09-08
Abstract: PURPOSE:To improve the potential distribution without changing the thickness of insulation among the turns by forming the specific permittivity of the insulating sheet to be wound on an inner circumferential side of a winding relatively larger than that of the insulating sheet to be wound on a peripheral side of the winding. CONSTITUTION:At the beginning of winding, an insulating sheet 2 which is e.g. the sheet made of a polyamide-group film having a large specific permittivity is wound on a foot part 3 of an iron core together with a metallic sheet 1. The winding is thus wound continuously and when the winding reaches the vicinity of the periphery, the winding is composed of at least one of a polyethylene-group film, a polystyrene-group film and a polyester-group film specific permittivities of which are relatively smaller than the sheet 2 used at the beginning of winding. Thus, the capacity among the turns can be made to be equal both in the inside and the outside of the winding and the potential distribution of the winding against rapid penetration of surge is improved.

Abstract: PURPOSE:To detect the precipitation state of powder in a suspension sotrage tank, i.e., the concentration of powder in the suspension, by enclosing ball shaped floats, which have different densities and the same outer diameters in many guide bars so that the floats can move only in the vertical direction. CONSTITUTION:When the concentration of suspension in a powder suspension storage tank is measured, a detecting device is inserted in the tank by a suspending wire 9. Then the device reaches the position at an arbitrary depth owing to the weight of a weight plate 3 against the buoyancy of the suspension. Meanwhile, of ball shaped floats 1a-1e having the different densities in guide bars 2, the ball shaped floats, whose density is smaller than the density of the suspension at the depth point, are floated and contacted with the lower surface of an upper plate 4. The floats, whose density is larger than that of the suspension is lowered and contacted with the weight plate 3. Float detecting terminals 5, which are embedded in the lower surface of the upper plate 4, detect the approach of the ball shaped floats and generate signals. The signals are displayed on a signal display device 11 together with a temperature signal from a temperature detecting terminal 6 through a connector 7 and a collecting cable 8.

Title: Mobile object allocating system and its method
Inventor: UNOKI TERUHIKO
IPC: G05D1/02
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To efficiently allocate a mobile object to a request source. SOLUTION: A position acquiring part 32 detects its own position and sends the detected position to a control center through a communication part 30. The center prepares information expressing the distribution state of mobile objects along a traveling route in an area based on the positional information of respective mobile objects and provides the prepared information to respective mobile objects. The communication part 30 receives the distribution information from the center and mutually communicates with respective requesting sources. A position specifying part 36 searches the shortest route up to each request source and calculates its route length.  A bidder selecting part 38 calculates the total number of mobile objects on each route based on the distribution information and calculates and stores an evaluation value for each bidder corresponding to the total number and the shortest route length. At the time of receiving a request message from a certain request source through the communication part 30, the selecting part 38 determines whether a bid message is to be transmitted to the request source or not based on the evaluation value corresponding to the combination of the shortest route length up to the request source and the total number of mobile objects on each route.

Title: Magnetic head cleaning card
Inventor: FURUHATA MORIO
IPC: G11B5/41
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To improve a cleaning effect of dust, dirt or the like by flocking a fluffing layer on one side of a polyester film, which fluffing layer comes as a wiping part into contact with a magnetic head surface over the entire part of the magnetic head surface having a curvature. SOLUTION: A flexible, transparent film which consists of polyethylene terephthalate or polyethylene naphthlate and has a thickness within a range of 40 to 350 μm is used for the polyester film. If the film thickness is below 40 μm, the handling quality at the time of producing the cleaning card or inserting the cleaning card into a reader/writer device is poor. If the film thickness exceeds 350 μm, the flexibility degrades and the cleaning effect degrades. The fiber flocks to be flocked on the polyester film surface are flocked at a flocking density ranging from 50 to 100 g/m<2> . If the flocking density is below 50 g/m<2> , the fiber flocks lay down and the cleaning effect degrades. If the flocking density exceeds 100 g/m<2> , the remarkable cleaning effect to the extent of meeting the difficulty in flocking or the like is not admitted.

Title: Optical transmission path
Inventor: SUGIE TOSHIHIKO
IPC: G02B6/10
Filed: 1991-07-04
Abstract: PURPOSE:To allow the incidence of a high photoelectric power signal and the long-distance transmission thereof by changing the Brillouin shift frequency of the introduced Brillouin scattering generated by the light signal propagated in an optical fiber in the propagation direction. CONSTITUTION:The intensity of the Stokes light which is backward propagated at the point of a distance L from the incident part of the optical fiber 14 for transmission changed in a Brillouin shift frequency is determined dependently upon a gain coefft. gB if the photoelectric power, the loss of the optical fiber and the effective core area are the same. The gain coefft gB is the function of the Brillouin shift frequency VB, Brillouin gain width and the refractive index of the optical fiber. Then, the structure in which the Brillouin shift ferquency VB is forcibly changed is obtd. by changing the optical fiber parameters, such as refractive index and doping quantity, and the photoelastic constant, etc., in the propagation direction, by which the conversion of the incident light on the conventional optical fiber to the backward propagated light is suppressed and the exponental functional increase is suppressed. The input limitation of the optical fiber is thus averted.

Title: Temperature sensor
Inventor: KANEKAWA HITOSHI
IPC: G01K3/10
Filed: 1989-06-27
Abstract: PURPOSE:To accurately grasp sudden change of temperature by forming a sensor so that the surface of a heat sink on the periphery of a sensor main body part may be convred with a heat insulating film. CONSTITUTION:A temperature sensor is constituted by attaching a substrate 1(sensor main body part) having temperature-sensing parts S and S' whose temperature-sensing characteristics are different to the heat sink 2. There are a diaphragm-like thin part and a thick part A' surrounding the thin part on the substrate 1. Then, the temperature sensing parts S and S' are provided on the thin part and the thick part A' respectively. The surface 2a of the heat sink on the periphery of the substrate 1 is covered with the heat insulating film 4. Therefore, the absorption of heat or the emission of heat which cause a sensing trouble between the heat sink 2 and atmosphere is suppressed on the periphery of the substrate 1. In the case that the temperature sensor receives the sudden change of temperature, the change of temperature directly occurs in a part near the surface 2a of the heat sink, thereby accurately grasping the change of temperature even though the substrate 1 is thin.
